Background: The study sought to learn about incidence and reasons for distal stent graft-induced new entry (dSINE) after thoracic endovascular aortic repair (TEVAR) or after frozen elephant trunk (FET) implantation, and develop prevention algorithms.
Methods: In an analysis of an international multicenter registry (EuREC [European Registry of Endovascular Aortic Repair Complications] registry), we found 69 dSINE patients of 1430 (4.8%) TEVAR patients with type B aortic dissection and 6 dSINE patients of 100 (6%) patients after the FET procedure for aortic dissection with secondary morphological comparison.
Results: The underlying aortic pathology was acute type B aortic dissection in 33 (44%) patients, subacute or chronic type B aortic dissection in 34 (45%) patients, acute type A aortic dissection in 3 patients and remaining dissection after type A repair in 3 (8%) patients, and acute type B intramural hematoma in 2 (3%) patients. dSINE occurred in 4.4% of patients in the acute setting and in 4.9% of patients in the subacute or chronic setting after TEVAR. After the FET procedure, dSINE occurred in 5.3% of patients in the acute setting and in 6.5% of patients in the chronic setting. The interval between TEVAR or FET and the diagnosis of dSINE was 489 ± 681 days. Follow-up after dSINE was 1340 ± 1151 days, and 4 (5%) patients developed recurrence of dSINE. Morphological analysis between patients after TEVAR with and without dSINE showed a smaller true lumen diameter, a more accentuated oval true lumen morphology, and a higher degree of stent graft oversizing in patients who developed dSINE.
Conclusions: dSINE after TEVAR or FET is not rare and occurs with similar incidence after acute and chronic aortic dissection (early and late). Avoiding oversizing in the acute and chronic settings as well as carefully selecting patients for TEVAR in postdissection aneurysmal formation will aid in reducing the incidence of dSINE to a minimum.

We present the case of a 74-year-old female patient with a 50 mm ascending aortic aneurysm who underwent ascending aorta replacement. During routine open heart surgery, suboptimal flow in the cardiopulmonary bypass circuit, led to the discovery of a type B aortic dissection with substantial flow in the false lumen. Conservative management was chosen, focusing on blood pressure control in the ICU.

Objective: We present our experience with endovascular Bentall procedure (Endo-Bentall) using a modular valve conduit (Endo-Bentall) in high-risk patients with aortic root pathologies.
Methods: The physician constructed Endo-Bentall device is composed of a self-expanding transcatheter aortic valve (TAVR), aortic endovascular stent graft (TEVAR), and two wire-reinforced fenestrations for coronary artery stenting. The TAVR valve is sutured into an appropriately sized TEVAR graft.

Objective: Over 30% of patients presenting with acute type A aortic dissection (ATAAD) are considered high - risk or inoperable. This study aims to investigate the early and mid-term outcomes of complex endovascular aortic repair of aortic root, ascending aorta, and aortic arch among patients with ATAAD.
Methods: From January 2018 to January 2023, 29 patients who were considered high risk for open operation underwent endovascular aortic repair.

Purpose: Acute aortic dissection is a serious cardiovascular emergency with a high mortality rate. Its pathogenesis is complex and remains unclear. This study aimed to assess the connection between the levels of genetically predicted circulating metabolites and the risk of aortic dissection.

Although open repair remains the mainstream treatment for aortic arch dissection, its surgical complexity and perioperative complications are significant. We developed a novel stentgraft system for less-invasive endovascular aortic arch repair. We successfully performed a total percutaneous transfemoral endovascular repair of aortic arch dissection using a novel off-the-shelf endograft system.
